Title:
  rpc.gssd memory leak

Status in nfs-utils package in Ubuntu:
  Fix Released
Status in nfs-utils source package in Lucid:
  Won't Fix

Bug description:
  rpc.gssd appears to be leaking a small amount of memory every time
  it's used to authenticate a kerberized nFS mount.  I can reproduce by
  running:

  while sleep 1; do mount -o sec=krb5 nfsserver:/remotepath /mnt; umount
  /mnt; done

  While running this in a loop, you can observe from rpc.gssd's
  /proc/<pid>/status file that its VmRSS grows indefinitely, generally
  by about 4 kB per mount request.  On some of our servers that have a
  high turn-over rate of kerberized NFS mounts, we've seen the rpc.gssd
  process grow to more than 600 MB!

  This happens on lucid with nfs-common 1:1.2.0-4ubuntu4.2.

  I haven't been able to reproduce on precise with nfs-common
  1:1.2.5-3ubuntu3, but this is still an important bug for lucid.
